RAC'USE, NEW YORK',` A CORPORATION OF PERFORATING DEVICE FOR CONESr Applicationnlea March 1e, 1925. y.serial No. 14,954.

This invention relates to a paper cone perforating device ofthe class set forth in a pending application, Serial 51,070, filed November 20, 1924, in which a hollow paper or equivalent cone is used as the supporting medium for a bobbin of yarn or other thread `to facilitate the coloring of portions of the yarn and mass by drawing the coloring matter through the porous mass of yarn by means of av suction .device inserted into or connected to the perforated' core in a manner somewhat similar to that shown in apendl ing application, Serial No. 751,069, .iled

November 20, 1924. j

It will be evident,however, that the same device maybe used forr perforating other objects without .departing from the spirit of theinvention.

The main object is to provide a simple andl eicient means for expeditiouslyperforating hollow fibrous objects such as paper cones either before o-r after yarn has been wound thereon and preparatory to coloring i portions ofthe yarn en masse without removing'it from the cone.

Another object is to provide simple and efficient means whereby the operation ofthe punching elements may be controlled by fiuid pressure from any available source, not shown. n

Other objects and uses relating to specific parts of the device and its controlling means will be brought out inthe following description. v

As illustrated,` this perforating device comprises a sleeve -61- mounted in the upper `portieri of an Vupright bracket -3-.- of a main-.supporting frame'-3- to extend Y beyond the offset ends of said bracket for receiving at its rear enda collar B2-.- and at its front end a tapered head G3-f corre' spending approximately to the size and form,

of the interior of the tapered core or bobbin @-s which is adapted to be placed thereonA and remo-ved therefrom by endwise sliding movement, the conical core j-V-abeing adapted to receive and support a mass of yarn -A-I- wound thereon.l l
